  THE 
  ZOOLOGIST. 
  

  

  group 
  of 
  insects, 
  these 
  notes 
  seem 
  to 
  have 
  been 
  ignored, 
  and, 
  to 
  

   take 
  the 
  Cicadas 
  for 
  example, 
  more 
  descriptive 
  names 
  are 
  recorded 
  

   than 
  species 
  really 
  exist, 
  as 
  has 
  been 
  pointed 
  out 
  years 
  ago. 
  

   But, 
  as 
  Capt. 
  Hutton 
  remarks 
  in 
  the 
  Preface 
  : 
  " 
  The 
  list 
  — 
  as 
  its 
  

   name 
  implies 
  — 
  is 
  an 
  index 
  only. 
  . 
  . 
  . 
  Also, 
  it 
  is 
  only 
  a 
  record, 
  

   not 
  a 
  revision." 
  The 
  Introduction 
  is 
  a 
  most 
  interesting 
  con- 
  

   tribution 
  to 
  the 
  zoology 
  of 
  New 
  Zealand. 
  The 
  historical 
  section 
  

   details 
  the 
  visits 
  of 
  well-known 
  naturalists 
  since 
  the 
  time 
  of 
  Capt. 
  

   Cook's 
  first 
  voyage. 
  Capt. 
  Hutton 
  states 
  again 
  and 
  proves 
  the 
  

   thesis 
  that 
  New 
  Zealand 
  is 
  not 
  an 
  oceanic 
  island, 
  and 
  to 
  account 
  

   for 
  the 
  various 
  elements 
  in 
  its 
  fauna 
  "it 
  is 
  necessary 
  to 
  assume 
  

   the 
  existence 
  of 
  a 
  former 
  continent, 
  either 
  in 
  the 
  Antarctic 
  

   regions 
  or 
  in 
  the 
  Pacific." 
  The 
  theory 
  of 
  submerged 
  continents 
  

   is 
  often 
  deprecated, 
  but 
  it 
  throws 
  light 
  on 
  many 
  biological 
  

   problems, 
  and 
  affords 
  an 
  apparent 
  — 
  frequently 
  the 
  only 
  — 
  ex- 
  

   planation 
  to 
  many 
  riddles 
  in 
  zoo-geography. 
  

  

  New 
  Zealand 
  Neuroptera. 
  By 
  G. 
  V. 
  Hudson, 
  F.E.S. 
  

  

  West, 
  Newman 
  & 
  Co. 
  

   Mr. 
  Hudson, 
  who 
  has 
  done 
  much 
  in 
  adding 
  to 
  our 
  knowledge 
  

   of 
  the 
  entomology 
  of 
  New 
  Zealand, 
  has 
  devoted 
  this 
  volume 
  to 
  

   the 
  order 
  Neuroptera, 
  in 
  which 
  he 
  has 
  included 
  the 
  Odonata 
  

   (Dragonflies). 
  The 
  principal 
  work 
  done 
  in 
  the 
  description 
  of 
  

   these 
  insects 
  has 
  been 
  accomplished 
  from 
  time 
  to 
  time 
  by 
  our 
  

   countryman, 
  Mr. 
  McLachlan, 
  whose 
  descriptions 
  are 
  generally 
  

   reproduced. 
  The 
  special 
  value 
  of 
  this 
  publication 
  is 
  in 
  its 
  

   account 
  of 
  the 
  habits 
  and 
  life-histories 
  of 
  many 
  of 
  the 
  species 
  

   enumerated, 
  which 
  comprise 
  "some 
  of 
  the 
  most 
  important 
  and 
  

   conspicuous 
  neuropterous 
  insects 
  " 
  inhabiting 
  the 
  rivers, 
  streams, 
  

   and 
  lakes 
  of 
  New 
  Zealand. 
  Another 
  element 
  in 
  unique 
  informa- 
  

   tion 
  is 
  an 
  appendix 
  on 
  the 
  insect- 
  food 
  of 
  Trout 
  in 
  that 
  country. 
  

   Eleven 
  coloured 
  plates 
  produced 
  by 
  the 
  process 
  of 
  chromo- 
  

   lithography 
  add 
  considerably 
  to 
  the 
  value 
  of 
  a 
  very 
  useful 
  book.
